Bayern Munich has started the Bundesliga brilliantly so far and faced tonight's match with four wins out of four possible.
Now there was a home meeting with Duisburg and it took only 21 minutes before Bayern took the lead through a certain Swede.
Amanda Ilestedt stayed ahead and scored her second goal of the season, which meant 1-0 to a strong home team.
Six minutes later, Viviane Asseyi extended to 2-0, before Lea Schüller nodded in the final score 3-0 from close range just before half time.
However, Bayern are no longer league leaders.
Wolfsburg beat Sand 4-0 and lead 17-1 in goal difference.
Bayern have 16-0.
